Kojic Acid Derivatives
Melanin is one of the most important pigments which exist ubiquitously from microorganisms to plants and animals. It is secreted by melanocyte cells and determines the color of skin and hair in mammalians. It protects the skin from photocarcinogenesis by absorbing UV sunlight and removing reactive oxygen species (ROS) (Gupta, 2006; Kim, 2005; Sapkota, 2011). It is formed by enzymatically cataly...
متن کاملStudies on glycolic acid metabolism by frcshwatcr bacterial
Measurements of uptake and mineralization of 14C-labeled glycolic acid by freshwater heterotrophs showed that respiration (mineralization) accounts for 69% of total uptake, and that the heterotrophic potential ( V,,,,, ) for glycolate is comparable with that for other commonly used substrates. Bacteria cultured from lake water showed uptake and mineralization patterns similar to those from the ...
متن کاملCombined kinetic studies and computational analysis on kojic acid analogous as tyrosinase inhibitors.
Tyrosinase is a key enzyme in melanin synthesis and widely distributed in plants and animals tissues. In mammals, this enzyme is related to pigment production, involved in wound healing, primary immune response and it can also contribute to catecholamines synthesis in the brain. Consequently, tyrosinase enzyme represents an attractive and selective target in the field of the medicine, cosmetics...

متن کاملStudies on the Metabolism of Kynurenic Acid
In preceding reports from this laboratory, kyneurenic acid was shown to be degraded by cell-free extracts of Pseudomonas Jluorescens (ATCC 11299B) with the formation of L-glutamic acid, Dand L-alanine, and acetic acid as the major end products (2, 3). Subsequently, tracer experiments with kynurenic acid labeled with Cl4 at various positions demonstrated that the carbon skeleton of glutamic acid...
